The use of 35S20 steel grade can have various advantages and disadvantages depending on the specific requirements and applications. Here are some points to consider:

1. High strength: 35S20 steel grade exhibits good mechanical properties, including high tensile and yield strength, making it suitable for applications requiring strong and durable components.
2. Wear resistance: It has good wear resistance, making it suitable for parts that are subject to abrasive forces or friction.
3. Machinability: 35S20 steel grade can be easily machined, making it suitable for manufacturing complex parts with tight tolerances.
4. Cost-effective: Compared to some other high-performance steel grades, 35S20 offers a good balance between cost and performance, making it a cost-effective choice for certain applications.

1. Low corrosion resistance: 35S20 steel grade is not highly resistant to corrosion or oxidation, which may limit its use in environments where corrosion resistance is crucial.
2. Limited impact resistance: It may have limited resistance to impact or shock loading, which may not be suitable for applications that require high impact resistance.
3. Limited temperature resistance: 35S20 steel grade is not suitable for use in high-temperature environments due to its low temperature resistance.
4. Limited versatility: While it offers good mechanical properties, its limitations in terms of corrosion and temperature resistance may restrict its use in certain industries or applications.

Industries that may use 35S20 steel grade include automotive, aerospace, construction, machinery, and equipment manufacturing. It can be used in the production of various components such as gears, shafts, bolts, nuts, fittings, and structural parts.
